Distribution of diastemas in the dentition of man

Technical Note: The Definition of New Dental Morphological Variants Related to Malocclusion

“…Lavelle's (1970) study of diastemata among 656 individuals found the majority of diastemata were between the maxillary third premolar and canine and the maxillary second incisor and canine. A study by Keene (1963) evaluating midline and canine diastemata (>0.5 mm) among 183 white males found the most common diastema location was between the maxillary canine and the third premolar (even more common than midline diastema). Keene also found that the majority of diastemata were between 1 and 3 mm in size.…”

“…While this study reports low heritabilities, many studies have documented population differences in the expression of the trait (Huang and Creath, 1995;Lavelle, 1970;McVay and Latta, 1984;Scott and Irish, 2017), which suggests the utility of the trait in bioarchaeology and forensic anthropology. Further, as several studies have illustrated prevalence rates of canine diastemata in different populations (e.g., Keene, 1963), this trait may have value in biological anthropological studies as well.…”

Remodelação estética do sorriso com resina composta e clareamento dental em paciente jovem: relato de caso

“…Pode até mesmo contribuir para o desenvolvimento de distúrbios psicológicos e comportamentais, levando o indivíduo a adotar um comportamento tímido, reservado e retraído 8 . Dentre as alterações relevantes na aparência estética, podemos citar o mau posicionamento dos dentes, seguido das alterações de cor e forma, e também a presença de diastemas entre os dentes 2,9 .…”

“…O sucesso funcional e estético está diretamente relacionado a um planejamento correto determinado pelo cirurgião-dentista na visão multidisciplinar, e este deve ter pleno conhecimento da odontologia adesiva e dos materiais restauradores resinosos. Claramente é necessário observar e planejar o caso corretamente, avaliando os contatos oclusais existentes em máxima intercuspidação habitual, e nos movimentos excursivos de lateralidade e protrusão 8 .…”

Conservative and esthetic management of diastema closure using porcelain laminate veneers

“…MMD can be defined as a space greater than 0.5 mm between the proximal surfaces of the two central incisors. 1 The space can be a normal growth characteristic during the primary and mixed dentition and generally is closed by the time the maxillary canines erupt. For some individuals, however, the diastema does not close spontaneously.…”
